Answer

Brief Explanations:

  • Analyze each option:
    • Option 1: DNA has deoxyribose, RNA has ribose. So this is incorrect.
    • Option 2: DNA is double - stranded, RNA is single - stranded. This is incorrect.
    • Option 3: DNA contains thymine (T), RNA contains uracil (U) instead of thymine. This is a correct difference that affects their functions (e.g., DNA's stability for storage, RNA's flexibility for various roles like translation).
    • Option 4: DNA is mainly in the nucleus, RNA is found in nucleus and cytoplasm (e.g., mRNA, tRNA, rRNA in cytoplasm for translation). So this is incorrect.

Answer:

C. DNA contains thymine, while RNA contains uracil.
